Dublin's rental crisis: RTB and the 2026 rent rules

Dublin rentals are scarce and pricey, but since March 1, 2026, tenants have stronger protections than most renters back in the States, as long as you know the rules and check that your landlord follows them.

The short version

New rules apply to tenancies that started on or after March 1, 2026. They bring rolling six-year tenancies, called a Tenancy of Minimum Duration, and tighter limits on when a landlord can end one [1][2].
Rent increases are capped at 2% a year, or inflation (CPI) if that's lower, for most private tenancies, new and existing [1][3]. The old Rent Pressure Zones have been replaced by this national system [1].
Your landlord must register your tenancy with the Residential Tenancies Board (RTB) within one month of the start date, and again every year [7].
A deposit can't be more than one month's rent [4], and you should get a signed, dated receipt.
Scams are common. Never pay a deposit for an apartment you haven't seen in person or by a live video call with someone who can prove they control it.

USD conversions use the Federal Reserve H.10 rate of October 30, 2026 (EUR 1 = USD 1.1163).

Why Dublin feels like the Bay Area, only rainier

If you've rented in Boston, Seattle or San Francisco, the Dublin market will feel familiar: too many people chasing too few apartments, open viewings with a line out the door, and landlords who can afford to be picky. Expect to compete with dozens of other applicants for a well-priced one-bedroom near the city center, and have your documents ready before the first viewing: passport, employment letter or contract, recent payslips, and a reference from a previous landlord (a US landlord reference is better than nothing).

We're not quoting average rents here, because they move quickly and vary a lot by neighborhood. The RTB publishes rent data, and the Rent Register described below lets you see what similar homes rent for.

The good news is that Irish law gives tenants real rights, and the 2026 reform added more. The RTB is the government body that registers tenancies, runs the dispute service and publishes guidance. Think of it as a mix of a state housing agency and small claims court for landlord-tenant problems.

The rules that changed on March 1, 2026

The Residential Tenancies Act 2004 is the law; the RTB's summaries are simplified, and the Act is the final word [1]. Here's what applies to a tenancy that started on or after March 1, 2026.

Six-year tenancies and your security

After six continuous months in the home, you get security of tenure, as long as the landlord hasn't served a valid Notice of Termination in that time [1]. In the first six months, a landlord can end the tenancy for any reason [1].

After that, the tenancy runs in rolling six-year cycles [2][3], and what the landlord can do depends on who they are:

Landlord type	Grounds to end the tenancy during the six years	Extra grounds at the end of a six-year cycle
4 or more tenancies, or a company	Only a tenant breach, or the home no longer suits your needs [1]	None of the sale, renovation, family or change-of-use grounds [3]
1 to 3 tenancies	Breach, unsuitability, a sale to avoid undue financial hardship, or the landlord or a close family member moving in [1]	Sale, family occupation, substantial refurbishment, or change of use [1]

So if your landlord is a big investment fund or a company, which is common in newer Dublin apartment buildings, you're in a strong position after six months. With a small "accidental" landlord, there's more room for them to sell or move family in.

Rent increases

The cap: rent can go up once a year, by no more than 2% or the CPI rate, whichever is lower [1][2].
New apartments (construction started after June 10, 2025) can rise in line with CPI without the 2% ceiling [1].
Resets to market rent: for tenancies from March 1, 2026, a landlord can reset the rent to market rate between tenancies only if the last tenant left by choice, breached their obligations, or the home no longer suited them. There's no reset after a no-fault termination [1]. A reset is also allowed at the end of each six-year cycle [1].
Existing tenancies: for tenancies in place on February 28, 2026, increases are capped at 2% or CPI, and market resets aren't allowed [1][3].

Landlords setting or reviewing rent must use the RTB Rent Register and give three comparable examples [1]. If you think your rent is above market, you can open a dispute with the RTB; an adjudicator can order repayment of overpaid rent and damages of up to EUR 20,000 (about USD 22,300) [1].

Tenancies that started before March 1, 2026

Older tenancies keep the earlier rules on ending a tenancy. A landlord can end one for six reasons: breach, unsuitability, landlord or family occupation, sale, substantial refurbishment, or change of use [1]. For tenancies that began before June 11, 2022, the landlord can end the tenancy for any reason at the end of a Part 4 or Further Part 4 term [1]. Read your lease and check the start date.

RTB registration: why it matters to you

Registration is the landlord's job, not yours [7], but it's worth checking:

Ask for the registration when you sign. A landlord must register a new tenancy within one month of the start date, then register again each year on the anniversary [7].
Check the register. The RTB runs a tenancy registration check on its website.
Watch for rent changes. The landlord must update the registration when rent or other details change [7].
Keep records. Save your lease, rent receipts, emails and photos of the apartment on move-in day.

An unregistered tenancy is a red flag. It can mean a landlord who cuts corners elsewhere, or, in the worst case, someone renting out a place they don't control. Late fees apply to landlords for each month a registration is late [7].

Deposits and notice periods

Deposits

A landlord can't ask for a deposit of more than one month's rent [4]. Make sure the amount is written down and that you both get a signed, dated receipt [4]. Separate rules also limit how much rent a landlord can ask for in advance; check the RTB's guidance before you hand over more than the first month's rent and the deposit.

When you move out, the deposit should come back as soon as possible, though not necessarily on moving day, because the landlord may need to inspect [4]. A landlord can keep some or all of it only for rent arrears, unpaid bills you were responsible for, damage beyond normal wear and tear, or not giving proper notice [4]. If you disagree, the RTB's dispute service handles deposit cases.

How much notice you must give

How long you've rented	Notice you give the landlord [5]	Notice the landlord gives you [6]
Less than 6 months	28 days	90 days
6 months to 1 year	35 days	152 days
1 to 2 years	42 days	180 days
2 to 4 years	56 days	180 days
4 to 7 years	84 days	180 days
7 to 8 years	84 days	196 days
8 years or more	112 days	224 days

A landlord's notice must be in writing and meet the legal requirements, and a copy goes to the RTB within 7 days [6]. Shorter periods apply in some cases, such as 28 days after a warning for an unfixed breach, or 7 days for serious anti-social behavior [6]. A text message saying "I need the place back next month" isn't a valid notice.

Spotting rental scams

Scammers love Dublin's shortage, and newcomers who are apartment hunting from overseas are their favorite targets. The classic setup: a beautiful, underpriced apartment, a "landlord" who's abroad and can't show it, and a request to wire the deposit to hold it.

Protect yourself:

See it first. View in person, or by a live video call where the person walks through the apartment and opens doors and windows on request.
Never pay in cash, by wire or by money app before you've signed and confirmed who you're dealing with.
Check ownership. Ask for the landlord's name and compare it with the lease and, once signed, with the RTB registration.
Be suspicious of urgency. "Three other people want it, pay today" is a pressure tactic.
Use a short-term rental for your first few weeks so you can view places in person. It costs more, but far less than losing a deposit.

If you get scammed, report it to the Gardaí (the Irish police) and your bank right away.

The American angle

No US deduction for rent. Your Irish rent doesn't reduce your US tax, but the foreign housing exclusion or deduction on Form 2555 may cover part of it if you claim the foreign earned income exclusion. The Form 2555 instructions list location-based housing limits; a US expat tax preparer can check whether it helps you.
Ireland's Rent Tax Credit can cut your Irish tax: up to EUR 1,000 (about USD 1,120) for a single person in 2026 (see our income tax guide).
Your US credit score doesn't travel. Irish landlords can't easily check it, so a strong employer letter matters more than your FICO.
Keep a US address for banks and mail, and an Irish one for Revenue and your landlord.
